error: failed to select a version for `k8s-openapi`.
    ... required by package `kimspect v0.0.45 (/tmp/renovate/repos/github/koithos/kimspect)`
versions that meet the requirements `^0.28` are: 0.28.0

package `kimspect` depends on `k8s-openapi` with feature `v1_31` but `k8s-openapi` does not have that feature.
help: there is a feature `v1_32` with a similar name
